Lab Grown Diamonds Description
While natural diamonds take tens or even hundreds of millions of
years to form deep in the Earth, lab grown diamonds can take just a
few weeks to form in a laboratory, drastically reducing
manufacturing time. At present, there are two main ways to make
cultured diamonds.
One is high pressure and high temperature. During diamond
cultivation, the pure toner is compressed into a growth capsule,
which is then placed in a culture chamber, day after day, at a
pressure of 5-6 gpa and extremely high temperatures (up to
1,300-1,600 °C). Eventually the carbon atoms join together to form
a diamond crystal.
The other is chemical vapor deposition. Breeding process of
chemical vapor deposition method is a diamond chip to be placed in
a vacuum box, and then in the chamber filled with a mixture of
hydrogen and methane gas, the gas provides a carbon atom, under the
pressure of certain heating, until the gasification of carbon atoms
on the thin layers and layers of sedimentary, like rain, forming
uniform diamond coating.
Characteristics Of Lab Grown Diamonds
| The Difference Between Lab Diamond And Natural Diamond |
| Attribute | Lab Grown Diamonds | Natural diamond | Distinction |
| Chemical composition | C(carbon) | C(carbon) | No |
| Refractive index | 2.42 | 2.42 | No |
| Relative density | 3.52 | 3.52 | No |
| Dispersion | 0.044 | 0.044 | No |
| Hardness value | 90 GPA | 90 GPA | No |
| Thermal conductivity | 2*103 W/M/K | 2*103 W/M/K | No |
| Thermal property | 0.8*10-6 K | 0.8*10-6 K | No |
| Light transmittance | DEEP UV TO FAR TR | DEEP UV TO FAR TR | No |
Resistivity | 1016 OHM-CM | 1016 OHM-CM | No |
Compressibility | 8.3*10-13 M2/N | 8.3*10-13 M2/N | No |
From a scientific point of view, lab grown diamonds are exactly the
same as natural diamonds, the only difference being where they are
formed.
Prospects And Advantages Of Lab Grown Diamonds
Currently on the one hand, the decline in global production of
natural diamond, synthetic diamond on the other hand, the demand
for superhard materials continue to increase, either from the
perspective of the demand of industrial demand or jewellery
industry point of view, the perfect replacement for lab grown
diamonds are natural diamonds, and the current overseas natural
diamond giant in artificial diamond products. Therefore, the
development prospect of the diamond industry is very good.
Cultured and natural diamonds, by contrast, are crystals made of
pure carbon that have identical physical, chemical and optical
properties and look the same on the outside. Under the condition of
the same quality, it also has the advantages of cost-effective and
sustainable development, which is very in line with the
personalized needs of the new generation of consumers to enjoy
their own light luxury, greatly reducing the purchase threshold of
consumers, so that the cultivation of diamonds has gained great
popularity.
